I have two listview the other one is consider as details for the first one, however the number of the row in the second listview determined by the first listview. The first listview has 3 columns one the first two are strings and the third one is the number of rows for the second listview, how can i add both of the listview? it sounds like 2D array but in listview.
I can not find a way to link two listviews.
here is the class for both lists:
public class LvwInfo
{
private string _command = "";
private string _saperator = ",";
//
private int _noSeg=0;
public int _NoSeg { get { return _noSeg; } set { _noSeg = value;} }
public string _Command { get { return _command; } set { _command = value; } }
public string _Saperator { get { return _saperator; } set { _saperator = value; } }
public LvwInfo(string cmd,string sp,int Noseg)
{
_command = cmd;
_saperator = sp;
_noSeg = Noseg;
}
}
public class LvwInfoSeg
{
private string _segm = "";
private string _variable = "";
private string _partly = "";
public string _Segm { get { return _segm; } set { _segm = value; } }
public string _Variable { get { return _variable; } set { _variable = value; } }
public string _Partly { get { return _partly; } set { _partly = value; } }
public LvwInfoSeg(string seg, string var, string par)
{
_segm = seg;
_variable = var;
_Partly = par;
}
}
}
and Here how i initilize them:
private List<LvwInfo> _lvwInfo { get; set; }
private List<List<LvwInfoSeg>> _lvwInfoSeg { get; set; }
I want to know how can i Add both list and link them together?

Now when I execute the query into a list using dapper
Connection conn = new Connection();
OracleConnection connection = conn.GetDBConnection();
myList= connection.Query<Batch>(querySql).ToList();
Now,while debugging, all fields returns the expected values .But, I noticed those fields below are null in myList not empty but really null , but the problem is they aren't null in the database
Bmdrubirique , Sunid, Bmdentrynbre, Bradid ,Cenid
In oracle database those fields are like the following :
CENID is VARCHAR2(3 BYTE)`
Bmhid is VARCHAR2(3 BYTE)
Sunid is NUMBER(38,0)
Bradid is VARCHAR2(3 BYTE)
I don't get it , where did it go wrong? why other fields are properly loaded while those returns null value ?
My default assumption would be that there is a typo in the real code and the constructor is assigning a value from a field to itself. However, frankly: since you have a public Batch() {} constructor, I'm not sure what the benefit of the second one is - it just adds risk of errors. Likewise with the fields and manual properties.
So if this as me, where you currently have (simplified to two properties):
public class Batch
{
private string cendid;
private string bmhfmc;
public Batch() {}
public Batch(string cendid, string bmhfmc)
{
this.cendid = cendid;
this.bmhfmc = bmhfmc;
}
public string Cendid
{
get { return cendid; }
set { cendid = value; }
}
public string Bmhfmc
{
get { return bmhfmc; }
set { bmhfmc = value; }
}
}
I would have literally just:
public class Batch
{
public string Cendid {get;set;}
public string Bmhfmc {get;set;}
}
All of the rest of the code is just opportunities to make coding errors.
Now: the reason that Cendid is null is because: the column is CENID - only one d. This means that dapper isn't even using your custom constructor, because it isn't a perfect match between the constructor and the columns. Ditto the other fields like BRAID vs BRADID.
So the next thing to do is to fix the typos.
Is there a standard naming convention for the properties/methods of a node/relationship class when working with Neo4jClient?
I'm following this link Neo4jClient - Retrieving relationship from Cypher query to create my relationship class
However, there are certain properties of my relationship which i can't get any value despite the relationship having it. While debugging my code, i realized certain properties was not retrieved from the relationship when creating the relationship object.
this is my relationship class
public class Creates
{
private string _raw;
private int _sourcePort;
private string _image;
private int _DestinationPort;
private int _eventcode;
private string _name;
private string _src_ip;
private int _src_port;
private string _dvc;
private int _signature_ID;
private string _dest_ip;
private string _computer;
private string _sourceType;
private int _recordID;
private int _processID;
private DateTime _time;
private int _dest_port;
public string Raw { get { return _raw; } set { _raw = value; } }
public int SourcePort { get { return _sourcePort; } set { _sourcePort = value; } }
public string Image { get { return _image; } set { _image = value; } }
public int DestinationPort { get { return _DestinationPort; } set { _DestinationPort = value; } }
public int Eventcode { get { return _eventcode; } set { _eventcode = value; } }
public string Name { get { return _name; } set { _name = value; } }
public string Src_ip { get { return _src_ip; } set { _src_ip = value; } }
public int Src_port { get { return _src_port; } set { _src_port = value; } }
public string DVC { get { return _dvc; } set { _dvc = value; } }
public int Signature_ID { get { return _signature_ID; } set { _signature_ID = value; } }
public string Dest_ip { get { return _dest_ip; } set { _dest_ip = value; } }
public string Computer { get { return _computer; } set { _computer = value; } }
public string SourceType { get { return _sourceType; } set { _sourceType = value; } }
public int RecordID { get { return _recordID; } set { _recordID = value; } }
public int ProcessID { get { return _processID; } set { _processID = value; } }
public DateTime Indextime { get { return _time; } set { _time = value; } }
public int Dest_port { get { return _dest_port; } set { _dest_port = value; } }
}
This is another class
public class ProcessConnectedIP
{
public Neo4jClient.RelationshipInstance<Pivot> bindto { get; set; }
public Neo4jClient.Node<LogEvent> bindip { get; set; }
public Neo4jClient.RelationshipInstance<Pivot> connectto { get; set; }
public Neo4jClient.Node<LogEvent> connectip { get; set; }
}
This is my neo4jclient query to get the relationship object
public IEnumerable<ProcessConnectedIP> GetConnectedIPs(string nodeName)
{
try
{
var result =
this.client.Cypher.Match("(sourceNode:Process{name:{nameParam}})-[b:Bind_IP]->(bind:IP_Address)-[c:Connect_IP]->(connect:IP_Address)")
.WithParam("nameParam", nodeName)
.Where("b.dest_ip = c.dest_ip")
.AndWhere("c.Image=~{imageParam}")
.WithParam("imageParam", $".*" + nodeName + ".*")
.Return((b, bind, c, connect) => new ProcessConnectedIP
{
bindto = b.As<RelationshipInstance<Creates>>(),
bindip = bind.As<Node<LogEvent>>(),
connectto = c.As<RelationshipInstance<Creates>>(),
connectip = connect.As<Node<LogEvent>>()
})
.Results;
return result;
}catch(Exception ex)
{
Console.WriteLine("GetConnectedIPs: Error Msg: " + ex.Message);
return null;
}
}
This is the method to read the results
public void MyMethod(string name)
{
IEnumerable<ProcessConnectedIP> result = clientDAL.GetConnectedIPs(name);
if(result != null)
{
var results = result.ToList();
Console.WriteLine(results.Count());
foreach (ProcessConnectedIP item in results)
{
Console.WriteLine(item.Data.Src_ip);
Console.WriteLine(item.bindto.StartNodeReference.Id);
Console.WriteLine(item.bindto.EndNodeReference.Id);
Console.WriteLine(item.connectto.StartNodeReference.Id);
Console.WriteLine(item.connectto.EndNodeReference.Id);
Node<LogEvent> ans = item.bindip;
LogEvent log = ans.Data;
Console.WriteLine(log.Name);
Node<LogEvent> ans1 = item.connectip;
LogEvent log1 = ans1.Data;
Console.WriteLine(log1.Name);
}
}
}
Somehow, i'm only able to populate the relationship object with src_ip/src_port/dest_ip/dest_port values. the rest are empty.
Is there any possible reason why? I've played with upper/lower cases on the properties names but it does not seem to work.
This is the section of the graph im working with
This is the relationship properties sample:
_raw: Some XML dataSourcePort: 49767Image: C:\Windows\explorer.exeDestinationPort: 443EventCode: 3Name: Bind
IPsrc_ip: 172.10.10.104dvc: COMPUTER-NAMEsrc_port:

13405621ProcessId: 7184_time: 2017-08-28T15:15:39+08:00dest_port: 443
I'm not entirely sure how your Creates class is ever populated, in particular those fields - as your Src_port property doesn't match the src_port in the sample you provided (case wise).
I think it's probably best to go back to a super simple version. Neo4jClient will map your properties to the properties in the Relationship as long as they have the same name (and it is case-sensitive).
So start with a new Creates class (and use auto properties - it'll make your life a lot easier!)
public class Creates
{
public string Computer { get; set; }
}
Run your query with that and see if you get a result, then keep on adding properties that match the name and type you expect to get back (int, string etc)
It seems that i have to give neo4j node/relationship property names in lowercase and without special characters at the start of the property name, in order for the above codes to work.
The graph was not created by me at the start thus i had to work on it with what was given. I had to get the developer who created the graph to create the nodes with lowercases in order for the above to work.
I am new to C# and was asked to create two class definitions (customer and order) using partial code and with the suggested class names, methods, contructors and following an example. I am not sure why I am getting so many errors when I build/debug?
After this is finished, I need to create another program that builds onto this one. Our instructor also asked us not to use validation...
Some of my most common errors are:

I have 3 Classes : Masina (Car), Destinatie (Destination) and MasinaDestinatie (CarDestination).
I need the third class to get the values of the car number _nr_masina and the destination _cod_dest through it's own constructor.
I need to make a constructor with parameters in the third class that stores the values of _nr_masina and _cod_dest.
Anyone know how can i do this exactly? I've tried making the private fields public and putting them as parameters but that doesn't work...
The classes:
namespace Problema_test
{
class Masina
{
private string _nr_masina = string.Empty;
private string _valoare = string.Empty;
private string _an_fabricatie = string.Empty;
public Masina(string nr_masina,string valoare, string an_fabricatie)
{
_nr_masina = nr_masina;
_valoare = valoare;
_an_fabricatie = an_fabricatie;
}
public string Numar
{
get { return _nr_masina; }
set { _nr_masina = value; }
}
public string Valoare
{
get { return _valoare; }
set { _valoare = value; }
}
public string Anul
{
get { return _an_fabricatie; }
set { _an_fabricatie = value; }
}
}
class Destinatie
{
private string _cod_destinatie = string.Empty;
private string _adresa = string.Empty;
public Destinatie(string cod_destinatie, string adresa)
{
_cod_destinatie = cod_destinatie;
_adresa = adresa;
}
public string CodDest
{
get { return _cod_destinatie; }
set { _cod_destinatie = value; }
}
public string Adresa
{
get { return _adresa; }
set { _adresa = value; }
}
}
class MasinaDestinatie
{
// how can i make this work?
public MasinaDestinatie(string numarMasina, string codDest)
{
}
}
}
You can store the values inside properties
class MasinaDestinatie
{
public string Numar {get;set;}
public string CodDest {get;set;}
public MasinaDestinatie(string numarMasina, string codDest)
{
Numar = numarMasina;
CodDest = codDest;
}
}
To use the class you have do something like this
var masina = new Masina("Dacia","2000","1992");
var destinatie = new Destinatie("123", "Romania");
var masinaDestinatie = new MasinaDestinatie(masina.Numar, destinatie.CodDest);
Solution 2: As #blas-soriano sugested you can store the reference of the objects (Masina, Destinatie), this way you won't have problems (i.e. CodDest exist only in MasinaDestinatie but not in Destinatie, and many others).
class MasinaDestinatie
{
private Masina _masina {get;set;}
private Destinatie _destinatie {get;set;}
public string Numar { get { return _masina.Numar; } }
public string CodDest { get { return _destinatie.CodDest; } }
public MasinaDestinatie(Masina masina, Destinatie destinatie)
{
_masina = masina;
_destinatie = destinatie;
}
}
To use the class you have do something like this
var masina = new Masina("Dacia","2000","1992");
var destinatie = new Destinatie("123", "Romania");
var masinaDestinatie = new MasinaDestinatie(masina, destinatie);

When i am doing
Collection<MTE> newMTE = new Collection<MTE>();
datagridview1.datasource= newMTE;
datagrid1.datasource = newMTE
on DGV i can see at all the string[] properties
on the datagrid i can see them but as property type and not as a value
image example:
http://farm6.staticflickr.com/5519/10725217114_226ddd96c7_m.jpg
my collection have millions of rows, so i need an easy to process solution.
thank you all for the help
newMTE is a collection itself and your string[] are collection of items too (string array).
You can use something like Grouping or Show Row Details to show subrows of a row.
Examples here:
